The contact portions are rotatable about respective axes. The main body unit moves along the floor surface as the contact portions rotate. Lines projected onto the floor surface and originating from the axes of rotation of the contact portions are spaced at substantially equal angular intervals. At most two of the axes are on a common plane. Each of the wheel units includes a motor base, a rotation drive motor supported on the motor base, a casing being rotatable relative to the motor base about related one of the axes and having related one of the contact portions, and a device for transmitting a rotational force generated by the rotation drive motor to the casing.

A leaning vehicle has a frame pivotally connected to the lower end of a shock tower, the pivotal connection defining a frame leaning axis wherein the frame is adapted to lean to a right side and to a left side relative to the shock tower about the frame leaning axis. The leaning vehicle includes an actuator operatively connected to the frame and to the shock tower which is adapted to impart a leaning motion to the frame relative to the shock tower about the frame leaning axis.

A leaning vehicle has a frame that pivots relative to a pivotable frame member about a pivot axis. A torque exerted on a steering assembly in a first direction causes the frame to pivot relative to the pivotable frame member in a second, opposite direction at least when the speed of the vehicle is above a first threshold speed, to steer the vehicle in the second direction. An actuator urges the frame toward an upright position when the frame is in a leaning position and a speed of the vehicle is below a second threshold speed. A method is also described, in which a torque is exerted on the frame in the direction opposite the steering torque when the speed above the first threshold speed. The torque exerted by the actuator is opposite the leaning angle when the speed of travel is below the second threshold speed.

A tilting suspension system is provided for two wheels (2, 3) of a vehicle (200) disposed on a common axle with the module comprising a rigid frame (17) adapted to be firmly fixed to the chassis of the vehicle so as to be tilted together with the whole vehicle and a tilting arm (14) pivotally linked to the rigid frame. The tilting of the rigid frame is obtained as a result of the counter torque arising when activating hydraulic actuating means (101, 102) pivotally interposed between the tilting arm (14) and the rigid frame (17), with the tilting arm being pivotally connected to shock absorbers (18). The tilting module further comprises suspension arms (10, 11, 12, 13) pivotally connected to the rigid frame, with the suspension arms supporting, in cooperation with supporting uprights, the two wheels thus allowing both tilting and steering of the two wheels. The hydraulic actuating means (101, 102) are actuated by a hydraulic pump (112) driven by an electric motor (108).

A body frame is divided into three, namely, a front assembly having a closed loop structure, an engine support system assembly having a closed loop structure and a rear suspension support system assembly having a closed loop structure. The front assembly and the rear suspension support system assembly are connected to the engine support system assembly to form the body frame. The small assemblies have a closed loop structure whereby the rigidity is enhanced, and the shape is also stabilized. Therefore, the accuracy management can be performed.

The amount of lean to be provided is determined by force sensors, the speed, and/or the angle of turn. Then the vehicle is leaned by actuators in the suspension in accordance with a predetermined protocol in an electronic control unit (ECU). The protocol also provides shock absorption by rapidly tracking a contour of a surface on which the vehicle rides. The suspension is provided by a plurality of arm assemblies each including a lower arm, an upper control arm, and an actuator motively connected to the lower arm and to the upper control arm. The arm assemblies are pivotally connected to the frame on a common axis. The arm assemblies generally form parallelograms and are actuated in concert to remain generally parallel to each other through a range of angles to adjust the lean of the vehicle. The arm assemblies are also actuated independently of each other to accommodate variations in the contour. In one aspect, an actuator controlled by an ECU can be replaced by a mechanical actuator that can be activated manually such as by a driver's own leaning weight.

In accordance with the present invention a vehicle comprises a tilting section and a hanging section both connected to each other.

A tilting suspension system is adapted for use with a vehicle having three wheels and a frame. The system has two sets of control arms, each set of control arms being pivotally connected to one side of the frame. An upright is pivotally connected to each set of control arms, each upright having a rotatable hub for allowing one of the wheels to be mounted thereto. Two rocker arms are pivotally connected to the frame, and a control link is pivotally connected to each of the rocker arms, such that pivoting of one rocker arm causes corresponding pivoting of the other rocker arm. A link member operably connects each rocker arm to a corresponding upright, such that pivoting of each rocker arm causes corresponding movement of the uprights. An actuator is configured to selectively pivot the rocker arms, such that actuation of the actuator pivots the rocker arms, thereby causing the frame to rotate about a generally longitudinal roll center and causing each upright to rotate about a generally longitudinal axis.
